This linear notch has been developed to avoid cross-type notches, and it is mainly in the late 1960s, patent No. 128968. A complementary star shape extends down to the complement of the screw head. The Torx® slot is so, the Torx® slot is straight, and the depth of the slot, or the wall commonly known as the wire head, is easy to split the whisker here.] A type contains a screw and a part and a The tools form the notches of the 1 '4 and 7 prefaces. The notches of different shapes are the notches. The transversely extending screwdriver is used. It has several disadvantages. Avoid these conventional disadvantages. Have a Philips® notch and a Torx® notch appears. In the axial direction, the walls of these screws are straightened by the substantially rounded corners. The tool ϋ eliminates reciprocating notches which still have some serious and will be restricted, especially countersunk heads. If the bottom is going to be a very tooled system; part of a screw system, as described in 〇. The earliest cross-screw head. To keep the leading edge flat, the new screw slot has Pozidrive® notches in these new screws. It is described in detail in the treatment of the slot with a missing point. The orientation of this notch is designed for disadvantages related to the notch. Even the disadvantages. Because the wall is too deep for the conical screw and the screw is thin, the screw head will be 3 M266371 because of the depth limitation 'the engagement between the notch and the tool will not be very good, and the tool is tightening or It will move when you loosen the screw. This restricted feeding between the tool and the screw can also cause the screw to disengage from the tool when the tool and screw are held approximately horizontally. It is important for a craftsman who will ## 丄 々 疋 a large number of screws to keep the screws on the tool until the screws are in the work material. As the tool wears, its energy to hold the screw becomes worse. Usually, a magnetic screwdriver bit is used to make it easier to hold the screw on the tool (bit). However, the cutter head can easily run out of the notch if the holding direction of the tool deviates from the axial direction of the screw. The depth of the notch is very small, and the cutter head and the notch have opposite margin limits within standard tolerances. In addition, not all screws are made of magnetic materials. Various attempts have been made in the design of screws, and these attempts can alleviate the above problems. A screw with a slot with a polygonal cross section is described in British Patent No. GB 2 3 29 947. One embodiment shows that a screw slot is made to have three steps on its screw head. The upper stage has the largest cross-sectional area, the second stage has a slightly smaller cross-sectional area, and the lower stage has the smallest cross-sectional area. All steps have a polygonal cross section. The tool for operating this screw has steps with different cross-sectional areas, each step being complementary to the cross section of one of the steps in the groove. A screw having a notch having substantially the same features as the notch described above is disclosed in British Patent No. GB1150382. However, this notch contains only two steps of M266371. The aforementioned screw notches have several serious disadvantages. Because all levels are designed to transmit the force, even a small 4 inaccuracy in the notch will cause the tool to fail to match one of the levels. Γ makes it difficult or even impossible to insert the tool into Notch +. Even if the tool can fit into the notch, it is still difficult to insert. The tool must be very carefully aligned with the ‘screw notches, which obviously takes a lot of time. Λ The screw slot of a raft design has the consequence of increasing manufacturing costs. However, these manufacturing costs are still relatively small compared to the cost of manufacturing a tool with the complexity of the aforementioned patent #. Therefore, the productivity of the tool is very high.疋 The use of the degree is a two-screw height, which is a disadvantage. Pull away from the screw cross section of the step that transmits torque by means of steps and screws to the hole European Patent No. DE 4413782, and a second hexagonal step wire with a straight wall at the bottom end. The shortcomings of the notch are foreign patent No. DE 4413782, such as the country. During the operation, if the work screw is used, the optical fixture will do the same. All the torque will have only a small strain compared to the first order. Will improve significantly. The danger of “rounding”. The European Patent No. EP 257664 discloses that there is no first type with a sloped 'top end with a circular or hexagonal cross section. Below this level. In addition to the system has the above For example, the complexity and the cost of the tool are too far to have a very serious first gradient step with friction in the axial direction. Passed through the second order. This many diameters, and the tool Therefore, there will be damage to the tool or the notch screw. M266371 The upper step is a traditional cross slot and the lower step is polygonal. A screwdriver for a cross slot screw or A special screwdriver can be used with this screw. This notch also has many disadvantages. This special screwdriver is complicated and expensive to manufacture and has the common disadvantages for all general tapered notches The screwdriver tends to move away from the axial direction of the screw. If so, the area of contact will be reduced and the strain on the notch and the screw will increase. In particular, the smaller the diameter under The step change will rise, and the tool or screw will be easily affected by this lack. [New content] The purpose of this creation is to provide a system including a slotted screw, where good contact is established on The screw and the space are used to keep the reel from being held on the tool without falling off, and a good contact between the screw slot and the tool can be achieved, because a small amount of the tool deviates from the screw Danger of damaging the tool due to the axial movement of the tool, one of which can be easily manufactured without increasing cost, and one of the traditional, standard tools can be used with the screw slot of this creation and have the same use as Traditionally, the effect of the notch is the same. One of the purposes of this creation is to achieve the above purpose without reducing the strength of the wall of a round head. According to this creation, this can be achieved by having a description in the patent application 1 , 4 or 7 to achieve the characteristics of the characteristics of the device. Straight wall of the above-mentioned screw. The points, such as the occurrence of a screwdriver on the screwdriver and a tool in which there will be no groove The opening is obviously in accordance with the standard range of taper screws No. 6 M266371 [Embodiment] An example shows a screw head with a Torx® slot. However, this creation is not limited to this type of slot and can be easily Suitable for other types of slots with straight walls. A plan view of a screw head with a Toirx® slot 2 is shown in Figure 3. The slot 2 is a recess in the screw head 3, which is made A star-shaped shape with six points and including rounded points 4 extending outward from an imaginary circle 5. A tool 6 (see Figures 1 and 2) will be associated with each point according to the direction of rotation One or the other side of 4 engages the contact surfaces 7 and 8. Figure 2 shows a section through the screw head 1. The recess 3 and its wall 9 are substantially straight and extend downward into the screw head 1. The cross section of the recessed portion 3 still maintains a star shape with six points throughout the portion of the straight wall. The depth of the recess 3 is limited by the minimum wall thickness 10 allowed for the recess 3 at the bottom. The screw slot 2 according to the present invention includes a further central recess 11 at the bottom of the six-point recess 3. The central recessed portion 11 has a circular cross section and a diameter much smaller than the diameter of the recessed portion 3. The wall 12 of the central recessed portion 11 may be straight, but is preferably slightly inclined so that the bottom portion 13 of the recessed portion 11 is slightly smaller than the diameter of the upper portion 14 of the recessed portion 11. A downwardly sloping transition surface 15 is formed between the upper portion 14 of the central recessed portion 11 and the wall 9 of the recessed portion 3. The tool 6 has an engagement region 16 which is designed to engage the recess 3. The shape of the engaging region 16 is complementary to that of the recessed portion 3, but has a diameter slightly smaller than the diameter of the recessed portion 37 M266371 to allow it to be inserted into the recessed portion 3 without difficulty. The tool has a center point 1 7 having a circular cross section. The diameter of this center point 1 7 is slightly smaller than the diameter of the center recessed portion 11. A surface 18 extends from the center point 17 to the engaging region 16. The inclination angle of the surface 18 is smaller than the inclination angle of the transition surface 15. Therefore, when a tool 6 is inserted into the notch 2, a space 19 is formed between the surfaces 15 and 18. The space 19 diverges towards the center point 17. This ensures the engagement of the tool with the wall 9 of the recess 3 over the entire height of the recess, thereby ensuring maximum engagement between the engagement area 16 of the tool and the recess 3. Furthermore, in the case of a surface-treated screw, the divergent space 19 can allow any excessive coating to be collected in the space 19 without interfering with the engagement between the tool and the slot . If not provided by the space 19, the residual coating will stop on the surface 15 and on the bottom 13 of the recess 11, thereby preventing a sufficient response between the tool 6 and the screw slot 2. The center point 17 and the recess 11 ensure a long and sufficient engagement between the tool 6 and the notch, and allow the screw to be held on the tool by friction without falling off. The angular movement (vibration) between the tool and the screw can also be reduced to a considerable extent. As shown, the center point 17 has a length shorter than the height of the recessed portion 3, so that the engaging region 16 of the tool 6 can be engaged with the recessed portion 3 before the center point 17 is engaged with the recessed portion 11. However, the tool may also have a center point 17 which is longer than the height of the recessed portion 3, so that the center point 17 8 M266371 can engage the recessed portion 11 before the engagement region 16 engages with the recessed portion 3. This facilitates the insertion of the tool into the notch, and when the center point 17 is inserted into the recess 3, it may hit the inclined transition surface 15 and slide into the recess 11. Therefore, the tool need only be rotated around the center point 17 to align the engaging region 16 with the recess 3. The screw slot does not discharge a conventional tool that does not have a center point 17 but the advantages provided by the center point 17 and the recess 11 cannot be obtained. Therefore, a screw with a notch based on this creation can be made regardless of the type of tool available to the craftsman, because the recess 3 is a conventional design, such as a Torx® notch. A craftsman who wishes to take advantage of the notch can simply purchase a tool based on this creation. [Brief Description of the Drawings] This creation will now be explained by referring to an embodiment shown in the drawings as an example, in which: FIG. 1 shows a carrying surface through a front end portion of a tool according to the creation; The figure shows a cross section through a screw head with one notch according to the present invention, which has been inserted into a tool according to the present invention; and FIG. 3 is a view of a screw head with one notch according to the present invention.
